Understanding the 2011 Japan Earthquake and Tsunami

On March 11, 2011, a magnitude 9.0 earthquake struck off the coast of northern Japan, triggering a devastating tsunami. The tsunami overwhelmed coastal defenses, causing widespread destruction and loss of life. The event was one of the largest recorded earthquakes globally. Tsunami waves, generated by tectonic plate movements, traveled at high speeds across the ocean, increasing in height as they reached shallow waters. Advanced technology, including GPS data, has provided valuable insights into the earthquake's dynamics, aiding future research and disaster prevention efforts.
